I would do it with a plugin. Set 'canpostattachment' to false. So, for the newreply page, I woud use the newreply_start hook location and do something like:

PHP Code:

if ($forumid == x)
$vbulletin->bf_ugp_forumpermissions['canpostattachment'] = false; 


x should be changed to the correct forumid. You can do something similar for other pages where attachments can be added (newthread.php page).
